build a gmaxx and i need help
 

hi guys. iam from the north, more exactly from sweden. i hope you understand my very very bad english.

my first question is about the chassi. im trying to find the G4 race chassi but its out of stock everywhere.
or should i use a FLM chassi?

this is my first of many, many questions...

thanks

Hi there!
no problems understanding you here...
Have you tried to write a mail directly to gorillamaxx abaout availability and when to expect new chassis in stock?
I personally prefer the g-maxx-chassis to the FLM-chassis due to the lower center of gravity.

Hope I could be of help and greetings to my Swedish neighbours form Germany. Neighbours in terms of "on the same continent" ;)

GorillaMaxx availability is somewhat worrying lately...

You can always start with the front and rear ends first, then make a decision on the chassis at a later date (opposite to the normal way of building a truck, but emaxxes are very universal with parts, so finding a suitable chassis, even if it isnt your ideal choice, wont be too difficult).

Welcome to RCM :smile:

thanks guys. i have send emails to GM but no answer..

yes i can order everythingels and then wait for the G4, but is it sure that GM will produce this chassi?

-what slipper shoulde i use with traxxas transmission(3905) some from RR? strobe?
-RPM suspension or traxxas own


i will use MMM 2200 but im not sure how many s with lipo, 4 or 6s?

Even if GM go out of business, you can still get an FLM chassis, or use the stock item until something else comes along.

With the 3905 tranny, you have to use the stock slipper as the RR or Strobe version only fits the older 3906 tranny- just tighten it up 99% and you should be fine.

As for suspension, thats very much personal choice. If you were deciding between just RPM and stock, I would go with RPM. Otherwise, there are many different aluminium suspension options- RPM arms and towers dont give you many options for tuning your ride height..

As for batteries, 4s lipo is fine for upto about 35-40mph with the MMM system, or if you want a bit more silly speed then 5 or 6s lipo. 5s lipo is alot of fun for bashing I've found, and leaves the esc with some overhead so you arent red-lining it constantly as such.

i was think of useing RPM arms an stock tower. tway other suggestion do you have?

I would go with FLM Towers, they are nice and adjustable, or even Nova Towers are nice too. Stock towers will continue to snap constantly IMO. As far as the GM chassis, have you tried Ebay at all? Otherwise, the extended FLM is nice too and cheap! ;)

i have decide me for a G4, i will wait.

Will the FLM towers fit on traxxas bulkhead?
my tought was to build with a lot of stock parts, bulkhead, diff, CVD. but maybe its stupid...

will the old emaxx trans. fit in the G4?

traxxas big bore shock, something to buy?suggestion?oil?spring?

Why would you want to use the old tranny if you could use the newer better one with better availabillity of spareparts and tuning parts? "edit, forgot that: no, the old tranny wouldn't fit in"
FLM-towers fit to the traxxas bulkheads, no problemo!
but if you are building your truck form scratch, I would go for FLM hybrid bulks so you could use 1/8 buggy/truggy diffs, well... actually that's what I did:yes:

concerning the shocks: I used the buggy shocks from ofna, wich UE sells as supershocks, but the traxxas bigbores might work as well.

as suspensionarms I used the ones from flextek, but RPM should be the best bang for the buck.


edit No.2:
That was the mail I sent gorillamaxx:
"Hi,
I wanted to ask when the G4 chassis are going to be in stock again since they are out of stock in every hobby shop I know and on your site as well."

and this was the reply:
"Yes - please check back near the end of next week. We are hope for a batch to be ready at that time.

George"

will all 1/8 diffs work in the hybrid bulk? just put the diff in? are all diffs ready to use or should i do somthing with them? my experience in this kind of work are werry small..

i liked the emaxx hard steal diff because it was so cheap. dont it work?isnt that the same diff as in the BL E-REVO? it should work

are the revo-diffs so much cheaper than the hot bodies diffs here in Mike's shop?
65$ including pinion and ballbearings sounds quite cheap to me.

to answer your first question: yep, more or less every 1/8 diff is a direct fit, at least I don't know any diffs that wouldn't fit.
If you are going to take the hot bodies diffs you should get the drivecups from HB and some shims as well...

ebay 20$
do i have to shims everydiff? i dont no how to do.
i can buy a new traxxas diff if it get broken.

about the shimming in the hybrid diffs I think yes, you have to shim every 1/8 diff in the hybrid bulkheads.
but the traxxas diffs don't fit into the hyybrid bulks.

I have to admit 20$ is cheap, but are the ball bearings and the pinion included?
and: I'm not shure if the traxxas diffs are holding up nearly as well as for example the HB diffs. Even with the new diffs from the revo and the new e-maxx 3905 I'm not shure.

do i put shims between the diff and the hybrid bulkhead?or IN the diff?
is the GM G4 the best bashchassi or should i take the FLM and make a total FLM truck with chassi hybrid bulkhead and tower? that is almoste the same price as an G4 chassi...
im just worried about the diff...
